IMPROVEMENT IN APPARATUS FOR REPRODUCING MOTION.

Specification forming part of Letters Patent No. 139,294, dated May 27,1873; application filed May 13,1873.

To all whom it may concern:

Be it known that I, CHARLES T. OHEsTEn, of Englewood, Bergen county, NewJersey, haveinvented a new and Improved Method I of Reproducing Motion,at any desired dis tance from the point where motion is produced,through the medium of atmospheric air, of which the following is aspecification, reference being had to the accompanying drawings formingpart thereof:

Figure 1 is an elevation of a cylinder, with its piston connected withmechanism, to which the piston communicates motion. Fig.

; 2 is a similar view of the cylinder and its I is produced, the forceemployed to produce the motion being communicated to the piston of anair-pump or cylinder, and thence transmitted to a second, andmay bedistant, airpump or cylinder, through an air-pipe or tube connecting thetwo cylinders, causing a corresponding motion in the piston of thesecond pump or'cylinder.

A B are two cylinders, into each of which is fitted a piston, air-tight.To piston-rod G is connected a pitman, a, that is actuated from thecrank-pin d in the wheel D.- The latter may be rotated. by the handle E.By these means a reciprocating motion may be given to the piston-rod.These two cylinders are pneumatically connected by the pipe G. ,It isevident that when the piston-rod is forced upward the air contained inthe cylinder, being thereby driven through the pipe G into the cylinderB, will force the pistonrod H downward, and that when the pistonrod 0 isdrawn downward, thus forming a vacuum in the cylinder A, the air theninthe cylinder B will rush back through the pipe G to fill it, andthepressure of the external air upon the under side of the piston H willforce that piston upward again. Thus, as the piston O is reciprocated acorrated at any desired distance from each other. When motion is thuscommunicated to the piston H it may be applied to a varietyof usefulpurposes. In the drawing it is represented as applied to producing anintermittent rotary motion of the wheel I by means of the lever J,pivoted at c upon a bracket, k, the lever being made to actuate the pawlL attached to thearm M .that'is pivoted at c, and engages with teeth inthe periphery of the wheel I. The movement of the piston-rod H may belimited either by a set-screw, f, stopping the arm M with a similarset-screw, j, above the said arm, or by adjustable collars g and it uponthe lower end of the piston-rod H, stopped either way by the bracket i.The motion thus communicated to the wheel I may be'employed for anydesired purpose; among others, that of turning on and off the gas from agas-burner, K as shown in the'drawing.

A single cylinder, A, may, by being constructed, relatively,sufliciently large, be made to operate any number of cylinders B throughbranch pipes leading from the main pipe G. I

It is evident that the method here described maybe very cheaplyandiconveniently applied to reproducing motion in mechanism at points sodistant from that where the motion is produced, that'to effect the sameresult by belts or. gearing or other equivalent mechanicalinstrumentality would I be impracticable or very expensive, and involvegreat intermediate loss of force.

I am of course aware that compressed air has been employed as a motor,and I do not claim, broadly, the producing of motion in mechanism by theexpansion of compressed air, nor by the pressure of the atmosphere uponone side of the piston when the counter balancing pressure of theatmosphere is removed from the opposite side.

What I do claim as my invention, and desire to secure by Letters Patent,is

1. The reproducing of a reciprocating mo tion, substantially in themanner, by the means, and for the purpose specified.

2. The combination of the cylinder and piston A O, and the actuatingmechanism E D a, with the cylinder and piston B H, as and for thepurpose specified.

3. The combination of the mechanism last above claimed with the wheel I,lever J, and pawl L, as and for the purpose specified.

Witness my hand this 16th day of December, 1871.
